' in connection with a conventional form of gasoline dispensing and measuring device and provided with coincontrolle mechanism for controlling a valve, and by means of which mechanism gasoline having a sales value accordin to the denomination of the coin placed in t e device, may be discharged from the device. a

A further object is to provide a coin controlled gasoline vending machine which may be operated upon the insertion of a coin. therein for dispensing gasoline to the value of the coin, and which will eliminate the necessity of maintaining an operator for the device. I

A further object is to provide the supply pipe with a valve having a control arm and float control means for. autqmatically closing the valve after an operation thereof, which 0 eration is'controlled by a coin placed within the machine.

A further object is to provide a spring motor operating shaft and provided with detent means coin controlled, and which shaft is provided with an arm which cooperates with the valve controllingbar for moving the valve to o n posit1on when the detent coin controlles means is tripped,

. and means for allowing a single revolution of the shaft and its-arm. v

A further object isto rovide a vertically movable frame to whic the float is connected bymeans of a rod and a plurality of vertically disposed shafts rotatably mounted in the frame, and which shafts are provided with arms normally in registration with the coin slots where said arms will be engaged by coins and the shafts rotated substantially ninety degrees when a coinis forced through any. of the slots. Also to provide detent means for holding the shafts in operative positions after a rotation thereof whereby pins carried by the shafts will engage and release the valve control bar upon an upward movement ofv the frame. The pins are positioned accord- .ing to the amount of gasoline-desired to be vendedfor the particular amount of coin placed 'inthe device.

. A further object is to provide anadjustable connection between the float carriedrod-and the frame whereby. the pins may be varied in position in relation to thevalve ect to provide Y device incident to fluctuation in price of gasoline.

With the above and otherob'ects in view the mvention resides in the com ination and arrangement -of parts as hereinafter set forth, shown in the drawin described and claimed, it being understoo that changes in the precise embodiment of the invention may be made within the scope of what is claimed without departing from the spirit of the invention.

Referring to the drawing, the numeral 1 designates the casing of a conventional form of gasoline dispensingdevice as at present in use, and supported on the upper end of the; casin into which gasohneis pumped in theusual manner through the pipe 3. The gasoline is discharged from the container .2 through the discharge pipe 4 and hose 5in the usual manner, therefore it will be seen that the dispensing device ma housed and manually operated for dispensing liquid without the coin control mechanism as hereinafter set forth if desired. Howeverthe normal using of the device may take place after the operatorhas rotated the valve 6 to a position where it will not stop the flow of gasoline through theoperation.

, One side of the casing 1 is rovided with an auxilia casing 7, and in w 'ch auxiliary pipe 3 during the pumping r casing isshdably mounted a frame 8, which frame "is rectangular shaped and comprises 1 is a glass container 2,

11, therefore it will beseen that-the frame is rectangularly shaped. Rocka-bly mounted in the frame 8 are vertically disposedshafts- 12, 13 and 14, which shafts extend upwardly through the frame to one side of the coin receiving slots 15, and are provided with arms 16, which normally register with the slots 15 and form closures therefor, and which arms are held in registering positions, by means of coiled springs 17, which are anchored to the shafts at 18 and to the frame 8 at 19, therefore it will be seen that when a coin is inserted in any of the slots"15the rock shafts will be rocked according to the denomination of the coin inserted, which action will cause an of the pivoted arms 20 to be moved inwar ly up to the inclines 21 carried by the lower bar 11 of the frame and the pivoted arm 20, which is carried by the shaft which has been operated, will drop behind the shoulder 22 carried by the bar 11, and will hold said shaft against retrograde rotation, and. will hold the pm 23 of the particular operated shaft in an outwardly extending position, substantlally at ninety degrees to its normal position, where the operated pin will engage the valve control lever 24 upon an upward movement of the frame 8 as a whole. After the coin passes through the coin receiving slots 15, it"enters one of the troughs 25, then into a hopper 26, therefore it will be seen no matter what denomination the coin may be it will enter the same hop er 26. Valve 6 is normally maintained in c osed position by means of the spring 27 which is anchored to the valve casing 28 and to the valve lever 29. The valve control bar 24 is pivot ally connected at 30 to the valve lever 29 and is slidably and loosely mountedin'an opening 31 in the adjacent side of the casing 1 and is provided with a shouder 32 adapted to hook over the ed e 33 in the bottom of the opening 31 for holding the valve 6 in open position against the action of the coiled spring 27.

The coin which is discharged from the hopper 26 enters a V-shaped dipper 34 which is carried by a release lever 35, which release lever is carried by a rock shaft 36 rotatably mounted in bearings of a frame 37. The under side of the dipper 34 is open and straddles the shaft 38, which shaft is rotated by a spring motor 39 through a gear train 40, however the shaft 38- rotates in the direction of the arrow a, Figure 7. Dipper lever 35 is normally in the position shown in Figures 7 and 8 and is provided with an adjust-able weight 41, whereby its flattened end 42 will be normally forced downwardly for overbalancing the dipper 34 and is in the fpath of an arm 43 carried by a countersha t direction of the arrow 6. Disposed above 44, which countershaft rotates in the the dipper arm 35 referably adjacent the dipper 34 is one oftli .ar train shafts 45, which shaft is rovid with an arm 46, which engages t e digpenarm 35 when the gear train is release when a coin is received in the dipper, thereby insuring a rapid downward movement of the di per into straddling engagement with the s aft 38 for projecting the coin from the dipper into the coin box 47. When the coin leaves the chute hopper 26, it drops into the dipper 34, forces the dipper 34 downwardly and the flattened end 42 of the arm 35 upwardly thereby releasing the shaft 44 and the gear train, which gear train will impart a rotation in the direction of the arrow 1: to the shaft 38. At the same time the shaft 45 will be' rapidly rotated thereby forcing the arm 46 into engagement with the dipper arm 35 which will force the dipper 34 down wardly to a position where the shaft38 will project the coin therefrom. The shaft 44 makes one revolution in the direction of the arrow b until the arm 43 engages the flattened portion 42, as the weight 41 immediately rocks the flattened end 42 of the lever 35 downwardly after the coin has been projected out of the dipper by the shaft 38. Shaft 38 is provided with a crank 48 at its outer end, which crank makes a complete rotation, and engages the notch 49- during its rotation of the valve control bar 24, moves the bar in the direction of the arrow 0 until the shoulder 32 receives the bottom edge 33 of the opening 31 in the casing 1, and which shoulder holds the valve 6 in open position, thereby allowing gasoline to be pumped upwardly through the pipe 3 in the usual manner and hold the valve 6 open against the action of the coiled As the liquid level in the receptacle 2 rises a float 50 moves upwardl which float is provided with a downwar y extending rod 51 which terminates in a horizontally disposed arm 52, which is adjustably connected at 53 to the slidable frame 8. It will be noted after an operation of the device by a coin, one of the arms 23 will be'loutwardly disposed as shown in Figure ,7, and as the frame 8 is raised by the float 50, said arm 23 will engage the bar 24, raise said bar slightly, thereby releasing the shoulder 32 and allowing the coiled spring 27 to move the va-ve 6 to closed position, thereby preventing further flow of gasoline to the receptacle 2. Arms 23 are located at different distances from the release bar 24 and consequently the liquid level which may be obtained in the receptacle 2 will be positively controlled according to the positions of the arms 23, therefore gasoline to the value of various coin denominations may be allowed to be dispensed. By adjustably connecting the arm 52 at 53 to the frame 8, the frame as a whole may be adjusted to take care of spring 27.

meager I fluctuation in the'selling fprice of gasoline bracket 58, and will move said plate u wardly, and the arm will cam pass t e same. After a valve releasing'operationof:

one of the arms 23, the frame 8 movesdownwardly incident to' the downward movement of the float 50 during the gasoline discharging operation, and the operated arm 20 will come into engagement with the hinged plate 57, which plate will be held in a horizontal position by the brackets -58 and therefore the arm 20 will be rocked on its pivotal point 20" to a plosition where it will not hold the operated s afts 12, 13 or 14 against rotation to normal inoperative position under the influence of the coiled springs 17.

' From the above it "will be seen that a gasoline vending device is provided which.

may be easily applied to a conventional form of dispensing machine and'gasoline may be vended in quantities according to the market price at the time.

To prevent the purchaser from beating the machine by placing a'coin in any of the slots 15 andoperating the valve 6 to open position and allowing simultaneous discharge of gasoline through the pipe 4, the discharge pipe is provided with a valve ,4 which is open when the valve 6 is closed and is closed when the valve 6 is open, therefore it will be seen that when the lever 24 is moved for opening the valve 6, the valve 4 will be closed, thereby preventing discharge of gasoline through the discharge pipev 4' until the lever 24 is engaged by one of the pins 23, and the valve 6 closed, at which time the valve 4- will be moved to open position by thelever 24 to the end of which is pivotally. connected at 4 the valve provided with 100 'ng lever 4. 7
